Objective: Over the past 20 years, significant investments have been made in managing historical releases of chlorinated solvents at Department of Defense (DoD) facilities. While these investments have not always achieved the desired results, knowledge has been gained about the behavior of chlorinated solvents in the subsurface and the effectiveness of emerging remediation technologies. In large part, these advances are attributable to DoD investments in research and development. Presently, there is an opportunity to enhance decision-making by highlighting current knowledge regarding best practices for management of chlorinated solvent releases. The objective of this project is to develop a protocol for selecting remedies for chlorinated solvent releases at DoD facilities that includes access to frequently asked questions (FAQ). Together, the protocol and FAQs will help DoD address lingering environmental legacy issues and focus on its core mission. Technology Description: The protocol and FAQs will provide a knowledge base, strategy, and methodology to guide parties involved in the selection, design, and implementation of remedies for chlorinated solvent releases at DoD facilities. The target audience includes DoD staff, consultants, regulators, and community representatives. Reflecting the needs of the target audience, the protocol will focus on providing concise, technically accurate information in a user-friendly way. It will be divided into the following three parts: (1) a stand-alone summary presented in the format of FAQs; (2) a comprehensive guide aimed at providing quick access to more detailed information; and (3) references to information and resources produced through ESTCP, SERDP, and other relevant programs. In a process consistent with the Resource Conservation and Recovery Act (RCRA) and the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), the protocol will guide decision makers in developing goals that are beneficial (from the risk/community perspective) and attainable (from a technical perspective). Critical to attainable goals is describing both the capabilities and limitations of current technologies, relative to specific endpoints, in a representative range of hydrogeologic settings. Expected Benefits: It is expected that the protocol for selecting remedies for chlorinated solvent releases will lead to better decisions and cost savings at multiple DoD facilities. It will serve as an easily accessible technology transfer vehicle that highlights DoD's investments in environmental science and technology. Lastly, the protocol has the potential to serve as a catalyst leading to more pragmatic policies for managing chlorinated solvents and other groundwater contaminants at DoD facilities.
